Staff & Ministry Leaders


Rev. Marshall Brown -  Senior Pastor

Marshall moved with his wife, Allison, to the North Shore in the spring of 2014 to become the Senior Pastor at Grace Presbyterian.  In 2015, Allison and Marshall became the proud parents of a son, Peter.  Prior to moving to Chicagoland, Marshall served as a pastor in Los Angeles and, before that, as campus minister (RUF) at the University of Alabama.  Before becoming a pastor, he worked in finance and education.  He is a graduate of Vanderbilt University (BA in History) and Reformed Theological Seminary (MDiv).  He likes to watch college football, play golf, travel with Allison, and wrestle with Peter.  Having lived in eight states and in three different time zones, the thing he appreciates most about the North Shore is the genuine Midwest kindness.

Missy Shinall - Director of Children's Ministries

After childhood in Ohio, Florida, and North Carolina, Missy graduated from The University of North Carolina at Chapel Hill with a degree in Psychology— Go Heels! She spent the next ten years working in development for educational organizations and cultural institutions in both Atlanta and Chicago, where she and her husband, Phillip, moved in 2004.  They have two daughters, Emma and Molly, and though they loved city life, the call of the suburbs was too powerful to resist, so they headed north to Winnetka in 2011.

Professionally, Missy’s role has often centered around one theme- connecting with people- and she's excited to join the staff at Grace to do just that. When not at church, Missy can be found trying new recipes, attempting to garden, soaking up art, music or theater wherever she can find it, and spending as much time as possible with her family-- preferably outdoors.

McKenna Rishmawy - Director of Connections

McKenna was born and raised in Orange County, California.  She attended Hope International University where she received her B.A. in social science along with her single-subject teaching credential and M.A. in education.  She spent several years working in her local community within the fields of education, ministry, and coffee.  She and her husband Derek spent several years leading the college ministry at Trinity United Presbyterian Church in Santa Ana, CA.  In 2015, she and Derek had the opportunity to move across the country for Derek's Ph.D. program in systematic theology at Trinity Evangelical Divinity School in Deerfield, Illinois.  In her spare time, McKenna loves to blog and write about beauty, practice bridal makeup, read, and eat her way around the city.


Molly Preston - Director of Women's Ministries

After graduating from Wheaton College with a degree in Literature and Political Science, Molly taught high school in rural Pennsylvania and worked in publishing in Manhattan where she met her husband Steve at Redeemer Presbyterian Church. Three weeks after their wedding a job change whisked them to Omaha, Nebraska, where they were involved in the first of several PCA church plants. Since then they have lived in Atlanta, Hinsdale, IL, Washington, DC, and Connecticut and raised five children, all of whom are now in college or high school. Molly is so thankful to have grown up with adults who loved the Bible, and so happy for the opportunity to "commend God’s works to the next generation.” She would love to have coffee, go for a (leisurely) bike ride, find out what your book group is reading, or ponder the mysteries of the teenage mind with you.


Jamie Herndon - Director of Youth Ministries

Stephen Simmons - Office Manager and Pastoral Intern



Joseph Luigs - Pastoral Intern for Youth

Joseph was born and raised for sunny days and beach bummin' in Orange County. But after graduating from BIOLA University with a degree in biblical and theological studies, he decided to brave the Chicago winter to work on his M.Div. at Trinity Evangelical Divinity School. He is interested in serious biblical/theological reflection towards dialogue with people of different worldviews and towards emotional/spiritual wholeness, especially amongst youth. Beyond the obvious enjoyment of reading dead theologians and languages, Joseph loves a movie with a good love story. And yes, his sports loyalties lie in Los Angeles.


Jeff Stevenson - Pastoral Intern

Jeff moved to the Chicagoland area in 2016 with his wife Pam to begin a second PhD in Intercultural Studies at Trinity Evangelical Divinity School (TEDS) and finish his MDiv from Reformed Theological Seminary (RTS). Jeff worked for Middlebury College for 10 years as the Director of the Middlebury School Abroad in Latin America (Mexico and Chile), which allowed him to live and minister as a “tentmaking” missionary there. He has worked with several international parachurch organizations and founded his own non-profit ministry, Proyecto Nehemías to produce Spanish-language materials for theological education and resilience in pastoral ministry. Jeff and Pam have three children ages 5 to 5 months. Jeff will be at Grace until June 2019 at which point they will transition as a family to Jeff’s native state of Washington where he will assume a position as senior pastor of a small Presbyterian church in the Cascade mountains (where Northern Exposure was filmed!).
